More help, im still confused

Answer:
a) [tex]\frac{1}{3}[/tex]
b) [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
a) the exponent is 2, therefore the value of [tex]\sqrt[2]{9}[/tex] would go in the place of the base.
b) the exponent is 2, therefore the value of [tex]\sqrt[2]{\frac{16}{25} }[/tex] would go in the place of the base => [tex]\frac{\sqrt{16}}{\sqrt{25}}[/tex] = [tex]\frac{4}{5}[/tex]
